Subject: patch 9.1.1573: Memory leak when pressing Ctrl-D in cmdline mode
X-Git-Tag: v9.1.1573^0
X-Git-Url: http://git.ipfire.org/gitweb/gitweb.cgi?a=commitdiff_plain;h=c02bef26fdfbffd442cbc5acef375256fa7fd6ff;p=thirdparty%2Fvim.git

patch 9.1.1573: Memory leak when pressing Ctrl-D in cmdline mode

Problem:  Memory leak when pressing Ctrl-D in cmdline mode
          (after 9.1.1571).
Solution: Free prev_cmdbuff before assigning to it.
          (zeertzjq).

Existing tests already cover this. This change fixes the CI failure.

closes: #17807
